Product Description:

The R2AA06020FXP11 is a medium-inertia servo motor produced by Sanyo Denki within the R SANMOTION Servo Motors series. Designed for industrial automation axes that require quick positioning and repeatable speed control, it couples directly to ball screws or timing pulleys through its keyed output shaft. A 60 mm flange facilitates attachment to compact machinery frames. The battery-backed absolute encoder retains multi-turn position data during power interruptions, so homing cycles are unnecessary after a restart.

The motor’s three-phase stator is optimized for a supply of 200 V, with which it delivers a continuous mechanical output of 200 W. Its rated torque is 0.637 N·m, generated at a rated armature current of 1.5 A rms; these values assist with drive sizing and thermal calculations for continuous-duty operation. The winding has a torque constant of 0.476 N·m/A rms, providing a predictable relationship between the current command and the resulting torque. An enclosure rating of IP67 protects internal components from dust ingress and temporary water immersion. This protection permits installation without a separate cabinet on equipment exposed to washdown conditions or airborne debris.

The rotor can reach 6000 rpm for rapid indexing and withstands a peak stall torque of 2.2 N·m during intermittent load demands without demagnetization. The encoder supplies single-turn feedback at 131,072 discrete positions, supporting precise position measurement and tight servo-loop gains. The motor has a mass of 0.96 kg, which limits the additional weight placed on robotic joints or gantry bridges. The unit is built without a holding brake or oil seal, so an external mechanism must secure vertical loads when power is removed. Its shaft should not be exposed to pressurized coolant because no oil seal is installed. A keyed steel output shaft provides positive torque transmission, while the medium-inertia rotor balances responsive acceleration with vibration control in multi-axis assemblies.
